Description

本発明は、回転電機の固定子に取付けられ、固定子歯に巻回される巻線を結線するバスリング、及びその取付構造に関する。   The present invention relates to a bus ring that is attached to a stator of a rotating electrical machine and connects windings wound around stator teeth, and an attachment structure thereof.

下記の特許文献に開示されたバスリングは、円弧状に湾曲された導電線材に門形(コの字形)の端子部を形成したものである。端子部は、環状の固定子の径方向に突出する形状であり、固定子歯に巻回された巻線が接続される。しかしながら、端子部の突出する分、バスリングの最外径の直径を大きくする必要があるので、固定子鉄心のコアバックの厚さよりも広い空間が必要となり、回転電機のハウジングの内径を大きくする必要が生じる。このため、回転電機の小型化が妨げられるという問題がある。   The bus ring disclosed in the following patent document is formed by forming a gate-shaped (U-shaped) terminal portion on a conductive wire curved in an arc shape. The terminal portion has a shape protruding in the radial direction of the annular stator, and is connected with a winding wound around the stator teeth. However, since the diameter of the outermost diameter of the bus ring needs to be increased by the amount of protrusion of the terminal portion, a space larger than the thickness of the core back of the stator core is required, and the inner diameter of the housing of the rotating electrical machine is increased. Need arises. For this reason, there exists a problem that size reduction of a rotary electric machine is prevented.

本発明の目的とするところは、回転電機の小型化に貢献するバスリング、及びその取付構造を提供することにある。   An object of the present invention is to provide a bus ring that contributes to downsizing of a rotating electrical machine and a mounting structure thereof.

本発明は、複数の固定子歯を円周方向に配列し回転電機の軸方向に端面を向ける固定子に、前記端面に沿わせて取付けられるバスリングであって、前記固定子よりも直径の小さな円弧状に湾曲した複数の導電線材を、互いに前記軸方向に位置を違えて配列し、前記導電線材に、その径方向へ延出するよう曲折された延出部を形成し、かつ前記導電線材に、前記延出部から前記軸方向へ突出する門形の曲折部を形成し、前記固定子歯に巻回される巻線が前記曲折部に接続されることを特徴とするバスリング。 The present invention is a bus ring that is arranged along the end surface to a stator in which a plurality of stator teeth are arranged in the circumferential direction and the end surface is directed in the axial direction of the rotating electrical machine, and has a diameter larger than that of the stator. A plurality of conductive wires curved in a small arc shape are arranged at different positions in the axial direction, an extension portion bent to extend in the radial direction is formed on the conductive wire, and the conductive A bus ring in which a gate-shaped bent portion protruding in the axial direction from the extending portion is formed on the wire, and a winding wound around the stator teeth is connected to the bent portion.

本発明は、巻線が巻回される複数の固定子歯を円周方向に配列し回転電機の軸方向に端面を向ける固定子に、前記端面に沿わせてバスリングを取付けるバスリングの取付構造であって、前記固定子よりも直径の小さな円弧状に湾曲した導電線材に、その径方向へ延出するよう曲折された延出部を形成し、かつ前記導電線材に、前記延出部から前記軸方向へ突出し前記円周方向の幅が前記軸方向へ突出するのに従って漸次に狭くなる門形の曲折部を形成したバスリングと、前記固定子歯と前記巻線との間に介在し、前記固定子の端面から前記軸方向へ突出する支持部を有するインシュレータと、両側を鉤状に曲げられ前記巻線の接続される金具とを備え、前記インシュレータの支持部を前記導電線材の内側に進入させた状態で、前記インシュレータに前記バスリングの導電線材を支持させ、前記金具の両側に前記導電線材の曲折部を挟み込ませ、前記金具を前記インシュレータの支持部に固定したことを特徴とする。 The present invention provides a mounting of a bus ring for mounting a bus ring along the end surface to a stator in which a plurality of stator teeth around which a winding is wound are arranged in the circumferential direction and the end surface is directed in the axial direction of the rotating electrical machine. A conductive wire curved in a circular arc shape having a diameter smaller than that of the stator, and an extension portion bent so as to extend in the radial direction is formed, and the extension portion is formed on the conductive wire. A bus ring having a gate-shaped bent portion that protrudes in the axial direction and gradually narrows as the circumferential width protrudes in the axial direction, and is interposed between the stator teeth and the windings And an insulator having a support portion protruding in the axial direction from the end face of the stator, and a metal fitting bent on both sides in a hook shape and connected to the winding, wherein the support portion of the insulator is attached to the conductive wire. In the state in which the Data on to support the conductive wire of the bus ring, thereby sandwiched the bent portion of the each side conductive wire of said fitting, characterized in that the bracket is fixed to the support portion of the insulator.

また、本発明は、前記インシュレータが、前記固定子の端面から前記軸方向に隔たる位置で、互いに軸方向に位置を違えて配列された複数の前記導電線材を支持し、前記複数の導電線材のそれぞれの曲折部が互いの位置を前記円周方向に違え、前記複数の導電線材のそれぞれの曲折部が前記軸方向に突出する長さを互に違えたことを特徴とする。 In the present invention, the insulator supports the plurality of conductive wire rods arranged at different positions in the axial direction at a position spaced apart from the end face of the stator in the axial direction, and the plurality of conductive wire rods The respective bent portions have different positions in the circumferential direction, and the respective bent portions of the plurality of conductive wire materials have different lengths protruding in the axial direction .

本発明に係るバスリングは、固定子鉄心の外径よりも直径の小さな円弧状に湾曲した導電線材に、回転電機の軸方向に突出する門形の曲折部を形成しているので、導電線材を固定子にその端面に沿わせて取付けた状態で、曲折部が固定子鉄心の径方向にはみ出すことがない。このため、回転電機のハウジング等として、固定子を収納できる最小限の大きさのものを適用すれば足りるので、回転電機を小型化することができる。   The bus ring according to the present invention forms a gate-shaped bent portion protruding in the axial direction of the rotating electrical machine on the conductive wire curved in an arc shape having a smaller diameter than the outer diameter of the stator core. The bent portion does not protrude in the radial direction of the stator core in a state in which is attached to the stator along the end face. For this reason, since it is sufficient to apply a minimum size housing that can accommodate the stator as the housing of the rotating electrical machine, the rotating electrical machine can be reduced in size.

しかも、本発明に係るバスリング、及びその取付構造は、門形の曲折部に、例えば巻線をねじ止めするための金具の取付けができる。このような金具に巻線を接続する作業は固定子の径方向の外方から行えるので、固定子によって作業者の手元が遮られることがなく、作業者は手際よく金具に巻線を接続することができる。また、導電線材に形成された複数の曲折部に巻線を接続する作業は、個々の曲折部の正面から行えるので、総ての曲折部に対して作業者は同じ要領で巻線を接続できる。このため、曲折部に巻線を接続する箇所を高品位に仕上げることが容易である。 In addition, the bus ring and the mounting structure thereof according to the present invention can attach a metal fitting for screwing, for example, a winding to the gate-shaped bent portion. Since the work of connecting the winding to such a metal fitting can be performed from the outside in the radial direction of the stator, the operator's hand is not obstructed by the stator, and the worker connects the winding to the metal fitting neatly. be able to. Moreover, since the operation | work which connects a coil | winding to the some bending part formed in the electrically conductive wire can be performed from the front of each bending part, an operator can connect a coil | winding with the same procedure with respect to all the bending parts. . For this reason, it is easy to finish the part which connects a coil | winding to a bending part in high quality.

また、回転電機が2相以上の巻線を備えるものである場合、複数の導電線材を互いに軸方向に位置を違えて配列すれば、導電線材が固定子の径方向にはみ出すことがない。このため、導電線材の数の多少に関わらず、回転電機を小型化することができる。更に、複数の導電線材のそれぞれの曲折部の位置を、互いに円周方向に違えるように複数の導電線材を配置すれば、曲折部同士が重なり合うのを避け、複数の導電線材のうち一つの導電線材の曲折部に上記の作業を行うとき、その他の導電線材の曲折部が邪魔にならないという利点がある。   Further, when the rotating electrical machine is provided with windings of two or more phases, the conductive wire does not protrude in the radial direction of the stator if a plurality of conductive wires are arranged at different positions in the axial direction. For this reason, a rotary electric machine can be reduced in size regardless of the number of conductive wires. Furthermore, if the plurality of conductive wires are arranged so that the positions of the respective bent portions of the plurality of conductive wires are different from each other in the circumferential direction, the bent portions are prevented from overlapping each other, and one of the plurality of conductive wires is electrically conductive. When the above operation is performed on the bent portion of the wire, there is an advantage that the bent portion of the other conductive wire does not get in the way.

更に、本発明に係るバスリング、及びその取付構造によれば、導電線材に径方向へ延出する延出部を形成し、この延出部を介して曲折部を導電線材に形成することにより、次に述べる絶縁距離を確保できる。即ち、複数の導電線材を互いに軸方向に位置を違えて配列する場合、これらの導電線材のそれぞれの延出部が径方向へ延出するので、導電線材同士を接近させても、複数の導電線材のうち一つの導電線材の曲折部と、その他の導電線材との間に、これらの絶縁に不可欠な絶縁距離を開けることができる。このため、回転電機を軸方向に不要に長くしないで済むので、回転電機を小型化することができる。 Furthermore, according to the bus ring and the mounting structure thereof according to the present invention, by forming an extended portion extending in the radial direction on the conductive wire, and forming a bent portion on the conductive wire through the extended portion. The insulation distance described below can be secured. That is, when a plurality of conductive wires are arranged at different positions in the axial direction, the respective extending portions of these conductive wires extend in the radial direction. Therefore, even if the conductive wires are brought close to each other, a plurality of conductive wires are arranged. An insulation distance indispensable for these insulations can be opened between the bent portion of one of the wires and the other conductive wires. For this reason, it is not necessary to lengthen the rotating electrical machine in the axial direction, so that the rotating electrical machine can be reduced in size.

また、曲折部がその円周方向の幅を、軸方向に曲折部が突出するのに従って漸次に狭くする形状であっても良い。この場合、例えば巻線を接続するための金具に、曲折部を進入させ曲折部の突出する向きに押せば、この金具に曲折部を挟み込ませられるので、曲折部に対して金具の位置決めを容易に行うことができる。   Further, the bent portion may have a shape in which the width in the circumferential direction is gradually narrowed as the bent portion protrudes in the axial direction. In this case, for example, if the bent portion is inserted into the metal fitting for connecting the winding and pushed in the protruding direction of the bent portion, the bent portion can be sandwiched between the metal fitting, so that the metal fitting can be easily positioned with respect to the bent portion. Can be done.

本発明に係るバスリングの取付構造によれば、複数の導電線材を固定子の端面から軸方向に隔たる位置で支持できる。この場合、複数の導電線材を互いに軸方向に違えるよう配置できるので、導電線材の数が増減しても、個々の導電線材が固定子の径方向にはみ出すことはない。このため、回転電機のハウジングは、固定子を収納できる最小限の内径を有するものであれば足りるので、回転電機の全体を小型化することができる。また、バスリングの曲折部が突出するのは軸方向であることから、インシュレータの支持部を導電線材の内側へ進入させるのに、曲折部の突出する分、導電線材の幅あるいは直径を大きくしないで済むという利点がある。   According to the bus ring mounting structure according to the present invention, a plurality of conductive wires can be supported at positions separated in the axial direction from the end face of the stator. In this case, since the plurality of conductive wires can be arranged to be different from each other in the axial direction, even if the number of conductive wires increases or decreases, the individual conductive wires do not protrude in the radial direction of the stator. For this reason, since the housing of a rotary electric machine should just have the minimum internal diameter which can accommodate a stator, the whole rotary electric machine can be reduced in size. Also, since the bent portion of the bus ring protrudes in the axial direction, the width or diameter of the conductive wire is not increased by the amount of protrusion of the bent portion to allow the insulator support portion to enter the inside of the conductive wire. There is an advantage that it is sufficient.

更に、本発明に係るバスリングの取付構造によれば、複数の導電線材のそれぞれの曲折部が軸方向に突出する長さを互に違えることで、個々の導電線材の曲折部と固定子の端面との間隔を所望に設定することができる。例えば、複数の導電線材のうち相対的に固定子の端面から離れているもの程、その曲折部を導電線材から軸方向へ長く突出させれば、上記の間隔を一様に揃えることができる。また、固定子歯と巻線との間に介在するインシュレータの支持部を、固定子の端面から軸方向へ突出させておけば、導電線材の内側にインシュレータを進入させた状態で、導電線材をインシュレータによって支持できる。この場合、導電線材を固定子に取付けするためのホルダー等が不要であるので、回転電機の部品点数を減らすことができる。 Furthermore, according to the mounting structure of the bus ring according to the present invention, the bent portions of the respective conductive wire members and the stators can be separated by changing the lengths of the bent portions of the plurality of conductive wire members in the axial direction. The distance from the end face can be set as desired. For example, the distance between the plurality of conductive wires that are relatively far from the end face of the stator can be made uniform by making the bent portion project longer in the axial direction from the conductive wire. In addition, if the insulator support portion interposed between the stator teeth and the winding is protruded in the axial direction from the end face of the stator, the conductive wire can be used in a state where the insulator has entered the conductive wire. It can be supported by an insulator. In this case, since a holder or the like for attaching the conductive wire to the stator is unnecessary, the number of parts of the rotating electrical machine can be reduced.

図1は、矢印Sで指した回転電機の軸方向に端面1を向けた環形の固定子3と、固定子3の端面1に沿う姿勢で固定子3に取付けられたバスリング5とを表している。固定子3は、矢印Rで指した円周方向に複数の固定子歯7を配列したものである。固定子3から取り外されたバスリング5が図2に表れている。上記の回転電機は自明の技術であるので、図示を省略しているが、そのハウジングの内側に固定子3を収納し、回転子と共に出力軸を回転させるものであれば良い。   FIG. 1 shows a ring-shaped stator 3 having an end face 1 directed in the axial direction of the rotating electrical machine pointed by an arrow S, and a bus ring 5 attached to the stator 3 in a posture along the end face 1 of the stator 3. ing. The stator 3 has a plurality of stator teeth 7 arranged in a circumferential direction indicated by an arrow R. The bus ring 5 removed from the stator 3 is shown in FIG. Since the above rotating electrical machine is a self-explanatory technique, it is not shown in the figure, but it is sufficient if the stator 3 is housed inside the housing and the output shaft is rotated together with the rotor.

バスリング5は、図2に示すように円弧状に湾曲された4つの導電線材9を備える。個々の導電線材9は、図3に示すように軸方向に突出する複数の門形の曲折部11が形成されている。ここで、円弧状とは、直径[φ]の円に倣う形状である。[φ]は導電線材9の直径を表し、図1に示す固定子3の外周面13の直径よりも小さく設定されている。導電線材9の材質は銅等の導体であり、導電線材9の表面は絶縁材で被覆されていても良い。導電線材9の断面は、円形、楕円、又は多角形でも良い。   As shown in FIG. 2, the bus ring 5 includes four conductive wires 9 curved in an arc shape. As shown in FIG. 3, each conductive wire 9 has a plurality of gate-shaped bent portions 11 protruding in the axial direction. Here, the arc shape is a shape that follows a circle having a diameter [φ]. [Φ] represents the diameter of the conductive wire 9, and is set smaller than the diameter of the outer peripheral surface 13 of the stator 3 shown in FIG. The material of the conductive wire 9 is a conductor such as copper, and the surface of the conductive wire 9 may be covered with an insulating material. The cross section of the conductive wire 9 may be circular, elliptical, or polygonal.

更に、導電線材9にその径方向へ延出する延出部15を形成し、延出部15を介して導電線材9に曲折部11を形成するようにしても良い。この場合、導電線材9の径方向の最も外側に外接する円の直径[φmax]が、固定子3の外周面13の直径よりも小さければ良い。   Furthermore, the extending part 15 extended in the radial direction may be formed in the conductive wire 9, and the bent part 11 may be formed in the conductive wire 9 via the extending part 15. In this case, the diameter [φmax] of the circle circumscribing the outermost side in the radial direction of the conductive wire 9 only needs to be smaller than the diameter of the outer peripheral surface 13 of the stator 3.

曲折部11は、図1に示す固定子歯7に巻回された巻線17が接続される部位であり、巻線17の端部をねじ止めするための金具等の取付けができる。曲折部11の円周方向の幅は、図4に示すように、曲折部11が軸方向に突出するのに従って漸次狭くなるのが好ましい。例えば、両側が鉤状に曲げられた金具19を、曲折部11に抵抗溶接する場合、金具19の内側に曲折部11を進入させるだけで曲折部11を金具19の内側に挟み込むことができる。これにより曲折部11に対して金具19を容易に位置決めできる。金具19は孔21を有し、後述の要領で巻線17の端部を接続されるものである。   The bent portion 11 is a portion to which the winding 17 wound around the stator tooth 7 shown in FIG. 1 is connected, and a fitting or the like for screwing the end of the winding 17 can be attached. As shown in FIG. 4, the circumferential width of the bent portion 11 is preferably gradually reduced as the bent portion 11 protrudes in the axial direction. For example, when the metal fitting 19 whose both sides are bent in a bowl shape is resistance-welded to the bent portion 11, the bent portion 11 can be sandwiched inside the metal fitting 19 simply by entering the bent portion 11 inside the metal fitting 19. Thereby, the metal fitting 19 can be easily positioned with respect to the bent portion 11. The metal fitting 19 has a hole 21 to which the end of the winding 17 is connected in the manner described later.

上記のように、曲折部11に金具19を位置決めする作業、及び金具19に巻線17を接続する作業は、固定子3の径方向の外方から行えるので、固定子3によって作業者の手元が遮られることがなく、作業者は手際よく金具19に巻線17を接続することができる。また、上記の作業は、個々の曲折部11の正面から行えるので、総ての曲折部11に対して作業者は同じ要領で巻線17を接続できる。このため、導電線材9に巻線17の端部を接続する総ての箇所を高品位に仕上げるのが容易である。   As described above, the work for positioning the metal fitting 19 in the bent portion 11 and the work for connecting the winding wire 17 to the metal fitting 19 can be performed from the outside in the radial direction of the stator 3. The operator can skillfully connect the winding 17 to the metal fitting 19 without being blocked. Further, since the above operation can be performed from the front of each bent portion 11, the operator can connect the winding 17 to all the bent portions 11 in the same manner. For this reason, it is easy to finish all the places where the ends of the windings 17 are connected to the conductive wire 9 to high quality.

図1,2に示す導電線材9の数を4つとしたのは、回転電機のU相、V相、W相、及びN相のそれぞれの巻線17を、1つの導電線材9に結線するためである。また、バスリング5は1つ以上の導電線材9を備えれば良く、回転電機の仕様により導電線材9の個数を増減しても良い。   The reason why the number of the conductive wire rods 9 shown in FIGS. 1 and 2 is four is to connect the windings 17 of the U-phase, V-phase, W-phase, and N-phase of the rotating electric machine to one conductive wire rod 9. It is. Moreover, the bus ring 5 should just be provided with the 1 or more conductive wire 9, and may increase / decrease the number of the conductive wires 9 by the specification of a rotary electric machine.

次に、図1,5に基づいて、1又は複数の導電線材9を固定子3に取付けるためのバスリングの取付構造23について説明する。固定子歯7と巻線17との間にはインシュレータ25が介在している。この点は総ての固定子歯7について同様である。インシュレータ25は、巻線17が巻回される合成樹脂製のボビンであり、固定子3の端面1から軸方向へ突出する板状の支持部27を有する。あるいは、インシュレータ25の支持部27のみを合成樹脂とし、支持部27と別体の絶縁紙を固定子3に巻き付けても良い。   Next, a bus ring mounting structure 23 for mounting one or a plurality of conductive wires 9 to the stator 3 will be described with reference to FIGS. An insulator 25 is interposed between the stator teeth 7 and the windings 17. This is the same for all stator teeth 7. The insulator 25 is a synthetic resin bobbin around which the winding wire 17 is wound, and has a plate-like support portion 27 protruding in the axial direction from the end surface 1 of the stator 3. Alternatively, only the support portion 27 of the insulator 25 may be made of synthetic resin, and insulating paper separate from the support portion 27 may be wound around the stator 3.

図1に表れた複数のインシュレータ25のそれぞれの支持部27は、互いに円筒状に連なり導電線材9の内側に進入する。この状態で、導電線材9はインシュレータ25によって支持されるので、導電線材9を固定子3に取付けするためのホルダー等が不要であり、回転電機の部品点数を減らすことができる。インシュレータ25に導電線材9を固定する手段は特に限定されないが、例えばねじ孔31と端子部32とが形成された巻線端金具30を、インシュレータ25の支持部27に固定しても良い。そして、図4に示す金具19の孔21にねじを通し、このねじを巻線端金具30のねじ孔31に締め付ける。これにより、導電線材9に位置決めされた金具19は、巻線端金具30を介して支持部27に固定される。巻線端金具30の端子部32は、巻線17の端部を接続される箇所である。符号29は、曲折部11の内側に嵌入することにより導電線材9を支持部27に位置決めするための爪部を指している。   The support portions 27 of the plurality of insulators 25 shown in FIG. 1 are connected to each other in a cylindrical shape and enter the inside of the conductive wire 9. In this state, since the conductive wire 9 is supported by the insulator 25, a holder for attaching the conductive wire 9 to the stator 3 is unnecessary, and the number of parts of the rotating electrical machine can be reduced. The means for fixing the conductive wire 9 to the insulator 25 is not particularly limited. For example, the winding end fitting 30 in which the screw hole 31 and the terminal portion 32 are formed may be fixed to the support portion 27 of the insulator 25. Then, a screw is passed through the hole 21 of the metal fitting 19 shown in FIG. 4, and this screw is tightened into the screw hole 31 of the winding end metal fitting 30. Thereby, the metal fitting 19 positioned on the conductive wire 9 is fixed to the support portion 27 via the winding end metal fitting 30. The terminal portion 32 of the winding end fitting 30 is a place where the end of the winding 17 is connected. Reference numeral 29 indicates a claw portion for positioning the conductive wire 9 on the support portion 27 by being fitted inside the bent portion 11.

また、インシュレータ25に支持された複数の導電線材9は、互いに軸方向に位置を違えているので、複数の導電線材9の数を増減させても、個々の導電線材9が固定子3の径方向にはみ出すことはない。このため、回転電機のハウジングは、固定子3を収納できる最小限の内径を有するものであれば足りるので、回転電機の全体を小型化することができる。また、曲折部11が導電線材9から突出するのは軸方向であることから、インシュレータ25の支持部27を導電線材9の内側へ進入させるのに、曲折部11の突出する分、導電線材9の直径を大きくしないで済むという利点がある。   In addition, since the plurality of conductive wire rods 9 supported by the insulator 25 are different from each other in the axial direction, even if the number of the plurality of conductive wire rods 9 is increased / decreased, the individual conductive wire rods 9 have the diameter of the stator 3. It does not protrude in the direction. For this reason, since the housing of a rotary electric machine should just have the minimum internal diameter which can accommodate the stator 3, the whole rotary electric machine can be reduced in size. Further, since the bent portion 11 protrudes from the conductive wire 9 in the axial direction, the conductive wire 9 is projected by the amount of protrusion of the bent portion 11 in order to allow the support portion 27 of the insulator 25 to enter the inside of the conductive wire 9. There is an advantage that it is not necessary to increase the diameter.

更に、バスリングの取付構造23によれば、複数の導電線材9のそれぞれの曲折部11の位置を互いに円周方向に違え、曲折部同士が重なり合うのを避けることができる。このため、複数の導電線材9のそれぞれの曲折部11に、巻線17を接続する作業を行うとき、複数の導電線材9のうち一つの導電線材の曲折部11がその他の導電線材9の曲折部11に遮られることがない。   Furthermore, according to the mounting structure 23 of the bus ring, the positions of the bent portions 11 of the plurality of conductive wires 9 can be different from each other in the circumferential direction, and the bent portions can be prevented from overlapping each other. For this reason, when performing the operation | work which connects the coil | winding 17 to each bending part 11 of the some conductive wire 9, the bending part 11 of one conductive wire among the some conductive wires 9 is bending of the other conductive wire 9. The part 11 is not obstructed.

更に、図6(a),(b)に示すように、延出部15が径方向へ延出する長さを[d]とし、曲折部11が軸方向へ突出する長さを[s]とする。インシュレータ25に支持された複数の導電線材9は、それぞれの延出部15の長さ[d]を有するので、図1,2に示すように、複数の導電線材9のうち一つの導電線材の曲折部11と、その他の導電線材9との間に、これらの絶縁に不可欠な絶縁距離が開けられている。このため、バスリングの取付構造23によれば、回転電機を軸方向に不要に長くしないで済むので、回転電機を小型化することができる。更に、複数の導電線材9のうち相対的に固定子3の端面1から離れているもの程、その曲折部11の長さ[s]を長くすれば、図1に示すように、固定子3の端面1と個々の導電線材9の曲折部11との間隔を一様に揃えることができる。   Further, as shown in FIGS. 6A and 6B, the length that the extending portion 15 extends in the radial direction is [d], and the length that the bent portion 11 protrudes in the axial direction is [s]. And Since the plurality of conductive wire rods 9 supported by the insulator 25 have the length [d] of each extending portion 15, as shown in FIGS. 1 and 2, one of the plurality of conductive wire rods 9 is one of the conductive wire rods 9. An insulation distance indispensable for these insulations is opened between the bent portion 11 and the other conductive wire 9. For this reason, according to the mounting structure 23 of the bus ring, the rotating electrical machine does not need to be unnecessarily lengthened in the axial direction, so that the rotating electrical machine can be reduced in size. Furthermore, if the length [s] of the bent part 11 is increased as the distance from the end face 1 of the stator 3 among the plurality of conductive wires 9 becomes relatively large, as shown in FIG. The distance between the end face 1 and the bent portion 11 of each conductive wire 9 can be made uniform.

尚、本発明は、その趣旨を逸脱しない範囲で当業者の知識に基づいて種々なる改良、修正、又は変形を加えた態様でも実施することができる。例えばバスリング5は延出部15を省略したものであっても良い。また、1つの導電線材9に形成される曲折部11の数が限定されることはない。   It should be noted that the present invention can also be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the bus ring 5 may have the extension portion 15 omitted. Moreover, the number of the bending parts 11 formed in one conductive wire 9 is not limited.

本発明は、回転電機に適用できるものである。   The present invention can be applied to a rotating electrical machine.
